T0 allwhom it may concern:

Be it known that I, HOWARD F. EoKER, aocitizen of the United States, residing at Baltimore, State of Maryland, have invented certain new and useful Improvements in Non-Refillable Bottles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to non-refillable bottles, and has for its object to provide a device of this character of novel and'eificient construction embodying an inwardly closing valve formed of buoyant material which will effectively prevent refilling of the bottle when inverted.

Another object is the provision ofanon refillable bottle including a simple and eiiicient guard device to prevent tampering with the valve of the bottle.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a side elevation of a bottle, showing the application thereto of the improved valve and guard and showing the cap and spring tongues in section. Fig. 2 represents a view similar to Fig. 1, showing the bottle in inverted position. Fig. 3 represents a transverse sectional view on the line 3-3 of Fig. 1, and Fig. 4 represents a side elevation of the guard member removed.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the body of a bottle of any preferred construction having the usual neck 6 provided adjacent its inner end with an internal shoulder 7 forming an abutment for a collar 8 formed of cork or other flexible material engaged Within an annular groove formed in the annular member 9. The collar 8 is snugly fitted within the groove in the annular member 9 and is frictionally engaged with the inner face of the neck 6 to retain the annular member in position and prevent the escape of liquid between said annular member and said neck. A plurality of outwardly directed pins 10 are secured in the outer edge of the annular member 9 and project toward the open end liquid from being or other ;buoyant material for a purpose ,which -w1ll;hereinafter, appear, and a flexible member 15 is secured longitudinally therethrough and looped in one of a series of links connecting the valve 11 with a weight 17. The weight 17 may be formed of-glassor any other suitable material and is formed at its outer end with a flared-i101- jlow enlargement lS havinga plurality of openings 19 therein permitting liquid to flow from .the body ,of the bottle The ifiared end 18 of the weight 17 is adapted to engage the inner end of the annular member 9 to limit the outward movement of the valve 11.

.A. guard designated generally by the nu meral 20 is arranged in the neck 6 of the bottle in spaced relation to the valve 11 and is secured in operative position by plastic material 25 positioned within grooves 21 formed in the circumferential edge of the body 22. The grooves 21 are preferably formed at diametrically opposite points in the circumferential edge of the body 22 and intermediate said grooves transverse recesses 23 are formed in said body to permit liquid to flow through the neck 6. Channels 25 are formed in the circumferential edge of the body 22 and communicating with the grooves 21 to allow part of the spring tongues 25 to lie flush with the edge of the body, when in opposite position. A cap 24 is positioned against the outer end of the body 22 and is formed with inwardly directed spring tongues 25 having inwardly turned inner extremities engaged within the diametrically opposed grooves 21 and embedded in the plastic material 25 to prevent the removal of the cap 2 1. The body 22 is formed with an integral stem 26 on the inner end of which is formed a circular plate 27 formed with transverse recesses 28 in its periphery arranged in staggered relation to the recesses 23 in the guard body 22 to prevent tampering with the Working parts of the valve.

In use, in its normal position the valve 11 is retained against .its seat 13 by the weight 17 and when the bottle is inverted to dispense the contents thereof, the flared end 18 of the wieght 17 engages the inner extremity of the annular member 9, as illustrated in Fig. 2, permitting the guard 11 to moveto open position. The liquid flows through the apertures 19 in the'fiare'd end 18 of .the weight, through the annular member 9 and the recesses 28 and 23 in the plate 27 and guard body 22 respectively. When the bottle 5-is restored to its normal position, as illustrated in Fig. 1, the weight of the member 17 automatically returns the valve 11 to closed position and prevents "tampering therewith. Should the bottle be guides, carried by said annular member, a

buoyant valve slidable in said guides, and

Copies of this patent may be obtained for adapted to cooperate with said annular said grooves securing said body in said neck, 1

a stem carried by the guard and provided with a plate at its inner end, a cap arranged outwardly of said body, and spring tongues carried by said cap extending inwardly in said channels and secured within said grooves by the plastic composition to prevent the removal of the cap.

In testimony whereof I afiix my signature in presence of two witnesses.
